US Patent:

8183824, May 22, 2012
Filed:

Jun 10, 2005
Appl. No.:

11/151163
Inventors:

Necdet Emek - Santa Clara CA, US
Mario Chunhwa Huang - Milpitas CA, US
Assignee:

Integrated Memory Logic, Inc. - Campbell CA
International Classification:

H02J 7/00
US Classification:

320107, 323234
Abstract:

In one embodiment of the present invention, a system includes a power stage component operable to generate an output voltage from a power source and to provide the output voltage to an electrical device. The power stage component is capable of operating in a plurality of modes depending on a level of the power source. An adaptive mode change component, coupled to the power stage, is operable to track at least one variation which affects the voltage across the electrical device and to generate at least one control signal for changing among the plurality of operating modes of the power stage component in response to the tracking.

US Patent:

20070008255, Jan 11, 2007
Filed:

Jun 10, 2005
Appl. No.:

11/150022
Inventors:

Necdet Emek - Santa Clara CA, US
Mario Huang - Milpitas CA, US
International Classification:

G09G 3/32
US Classification:

345082000
Abstract:

According to an embodiment of the present invention, a system is provided for driving at least one light-emitting diode (LED). The system includes an output terminal connectable to an anode of the LED and at which an output voltage can be provided for the LED. A driver loop, connectable to a cathode of the LED, is operable to maintain a LED current flowing through the LED at a desired level, thereby attenuating modulation error attributable to voltage variations at the cathode of the LED.
